The pretty basic. If you want to know the temp of the fluid in the return line, put it there.

If you want to know the temperature of the fluid going to the cooler, put it there.

If you want to know the temperature of the transmission, put it there.

I want to know how hot the transmission is.

Was just talking about this in PMs with somebody and thought I'd ask the question here since this has been a good discussion. What "problem" are we solving with supplemental cooler? Is it as simple as cooler is better (the corollary of bigger is better that you see in other parts of builds)? Or is it that fluid can get too hot such that it is not at the "right" temperature when it exits the stock cooler in the radiator? I think the answer to that is important to how a cooler should be installed.

personally, I found my Jeep didn't come with a stock transmission "cooler". I installed an auxiliary cooler because the stock "pass-thru" wasn't doing jack squat to "cool" the fluid to a reasonable operating temperature.

You'll have to define reasonable. My trans guy whom I trust more than should be legal tells me that unless it's seeing 250F sustained, quit worrying about it.

Lol. Still sounds like both of you guys agree with my thoughts (and what that means for cooler install).

After having the 42RLE rebuilt under warranty at 52k miles, I started wondering. Installed a temp gauge and saw 250F sustained just driving around town on hot days. Hence, I was worried and installed an actual cooler.

Reasonable to me is 120-180, depending on ambient temps and load, I can stay within that range the majority of the time now. I'll see ~200 when towing, and I'm ok with that.

Since blowing my new tranny replacement pan up while welding the temperature bung into it last year, I still don't have a temp sender so I only know when my transmission is getting warm by the cooler fan kicking on via its 165 degree thermostat. Though I welded my first bung into the 32RH pan without issue in my previous TJ, this last horrendously failed attempt spooked me so bad I'm going to pay Blaine to weld it into the new pan for me this time.

Getting Savvy...

When you have a choice, buy American.

If it's a 42, just buy the bung and I'll get it handled. I like handling bungs.

Lol. That's the best one I've heard since Thanksgiving when Dave C. was giving Wayne a hard time about liking to smoke meat.

So you're saying I can have Blaine pick up a new pan and weld a bung in it for me then ship it to FL? Lol

Close. I silver braze these in all the time. I've done about 20 of them for folks. If I acquire and ship you a pan, it's 200 bucks. If you ship me a pan and I modify it and ship it back, it's about 35 or so. If you have prepaid shipping, send the bung, and the pan, I'll do it for 10 bucks.

Don't ask me to repeat or remember those prices, I may be grumpy tomorrow and either double them or quit altogether.

That would be quicker than me doing it myself, I still have parts sitting in the garage from winter.

Right.... The radiator pass through is more of a fluid warmer than a fluid cooler IMO. You folks in cold climates need that for winter driving.... I didn't even bother with using it here in Cali.
